Hi, I am a nineteen year old female in generally good health. I have never had any serious medical conditions. About six weeks ago I took a trip to the emergency room with severe pains in my chest, almost under my breast bone. The doctors took several tests, including blood samples, and an EKG, and an X-ray. They found nothing abnormal, and ruled out that it must be dry pleurisy. They told me to take 800mg ibuprofen for a week. Six weeks later, and I still have these random pangs in my chest. It radiates to my back ,and switches from place to place in my general upper body area. I want to know, could these symptoms be something besides pleurisy? Also, is it normal for pleurisy to last this long? Any answers and I'll take them. Thank you.
